VPN, proxy, or Tor – which should you use? This guide explains how each technology works, their strengths and weaknesses, and which is best for different situations.
Quick Answer
VPN: Best for most users. Encrypts all traffic, fast speeds, easy to use. Use for everyday privacy and streaming.
Proxy: Hides IP only, usually no encryption. Use for quick, low-stakes tasks.
Tor: Maximum anonymity but very slow. Use when anonymity is critical and speed doesn’t matter.

How Each Technology Works
VPN (Virtual Private Network)
A VPN creates an encrypted tunnel between your device and a VPN server. All your internet traffic passes through this tunnel.
The process:
- Your device encrypts all outgoing traffic
- Encrypted traffic travels to the VPN server
- VPN server decrypts and forwards it to the destination
- Responses return the same way, encrypted
Websites see the VPN server’s IP, not yours. Your ISP sees encrypted traffic to one IP, but can’t see what you’re doing.
Proxy Server
A proxy is an intermediary server that forwards your requests. Unlike a VPN, it typically handles only specific traffic (like web browsing) and usually doesn’t encrypt.
The process:
- Your browser sends requests to the proxy server
- Proxy forwards the request to the website
- Website responds to the proxy
- Proxy sends the response back to you
Websites see the proxy’s IP, not yours. But without encryption, anyone monitoring your connection can see your traffic.
Proxy types:
- HTTP Proxy: Only handles web traffic
- HTTPS Proxy: Supports encrypted websites
- SOCKS Proxy: Handles any type of traffic
- SOCKS5: Adds authentication support
Tor (The Onion Router)
Tor routes your traffic through multiple volunteer-operated servers (nodes), wrapping it in layers of encryption like an onion.
The process:
- Your traffic is encrypted in 3 layers
- First node (guard) removes outer layer, sees only the next node
- Middle node removes second layer, knows nothing about origin or destination
- Exit node removes final layer, sends traffic to the website
- No single node knows both your identity AND destination
This distributed trust model means even compromised nodes can’t fully identify you.
Detailed Comparison
| Feature | VPN | Proxy | Tor |
|---|---|---|---|
| Encryption | Yes (AES-256) | Usually No | Yes (layered) |
| Speed | Fast (5-15% slower) | Fast | Very Slow (70-90% slower) |
| Traffic Coverage | All device traffic | App-specific | Browser only* |
| Anonymity Level | Good | Basic | Excellent |
| Trust Required | VPN provider | Proxy operator | Distributed (none) |
| Cost | $3-12/month | Free to Paid | Free |
| Ease of Use | Very Easy | Easy-Moderate | Easy (just use browser) |
| Streaming | Excellent | Limited | Not Practical |
| Torrenting | Supported | SOCKS only | Strongly Discouraged |
*Tor can protect all traffic with special configuration, but Tor Browser is the common use case.
Security Deep Dive
VPN Security
Strengths:
- Strong encryption (usually AES-256, the same as banks)
- Protects against ISP surveillance
- Secure on public WiFi
- Kill switch prevents leaks if connection drops
Weaknesses:
- Single point of trust – you must trust the VPN provider
- VPN company could theoretically log your activity
- Government could compel VPN to hand over data (if it exists)
Best practices: Choose a VPN with a verified no-logs policy, preferably audited by third parties, based in a privacy-friendly jurisdiction.
Proxy Security
Strengths:
- Hides your IP from websites
- Can bypass geo-restrictions
Weaknesses:
- No encryption (traffic can be intercepted)
- Proxy operator sees all your traffic in plain text
- Free proxies often log data, inject ads, or worse
- Doesn’t protect non-browser traffic
Warning: Never use free public proxies for anything sensitive. The proxy operator sees everything.
Tor Security
Strengths:
- No single point of trust – security doesn’t depend on trusting any one entity
- Resistant to traffic analysis
- Even compromised nodes can’t fully identify you
- Free and open source
Weaknesses:
- Exit node sees unencrypted traffic (if site isn’t HTTPS)
- Vulnerable to timing attacks with enough resources
- Using Tor can attract attention
- Many websites block Tor exit nodes
Best practices: Only use Tor Browser (not regular browser with Tor), don’t maximize the window (fingerprinting), don’t download files through Tor.
Speed Comparison
Real-world speed impact varies, but here are typical expectations:
| Technology | Speed Impact | Typical Use |
|---|---|---|
| VPN | 5-20% slower | HD streaming, gaming, downloads |
| Proxy | Minimal (0-10%) | Browsing, light streaming |
| Tor | 70-90% slower | Basic browsing, reading |
Why Tor is slow: Traffic bounces through at least 3 nodes, often on different continents, each adding latency. Nodes are volunteer-operated with varying bandwidth.
Why proxies are fast: No encryption overhead, direct path to destination.
Why VPNs are reasonably fast: Modern encryption is efficient, and commercial VPNs invest in fast servers.
Use Case Recommendations
Choose VPN For:
- Streaming geo-restricted content (Netflix, BBC iPlayer, etc.)
- Public WiFi protection
- General privacy from ISP
- Torrenting (with a VPN that allows it)
- Online gaming (DDoS protection)
- Working remotely
- Everyday privacy needs
Choose Proxy For:
- Quick IP changes for low-stakes tasks
- Bypassing simple geo-blocks
- Web scraping
- Testing website accessibility from different locations
- When you need speed and security isn’t critical
Choose Tor For:
- Maximum anonymity (whistleblowing, journalism)
- Accessing .onion sites
- Circumventing censorship in restrictive countries
- When you don’t trust any single provider
- Researching sensitive topics
Combining Technologies
VPN + Tor (Tor over VPN)
Connect to VPN first, then use Tor Browser.
Benefits:
- ISP can’t see you’re using Tor
- Extra layer of protection if Tor entry node is compromised
- Access Tor in countries that block it
Drawbacks:
- Even slower than Tor alone
- VPN can still see you’re using Tor (if they log)
Tor + VPN (VPN over Tor)
Use Tor first, then connect to VPN through Tor.
Benefits:
- VPN can’t see your real IP (only Tor exit node IP)
- Destination sees VPN IP (avoids Tor blocks)
Drawbacks:
- Complex to set up
- Very slow
- Requires VPN that accepts Tor traffic
Recommendation: For most users, Tor over VPN is simpler and provides good protection. VPN over Tor is for advanced users with specific threat models.
Common Mistakes
Trusting Free Proxies
Free proxy lists are often operated by people harvesting data. Your unencrypted traffic passes through their servers – they can see passwords, inject malware, or sell your browsing data.
Thinking Tor Makes Everything Anonymous
Tor hides your IP, but if you log into your personal accounts or use identifying information, you’ve defeated the purpose. Anonymity requires consistent behavior.
Using Tor for Torrenting
Torrent traffic bypasses Tor and reveals your real IP. Even if routed through Tor, it overloads the network (which is maintained by volunteers) and is considered abuse.
Assuming All VPNs Are Equal
VPN quality varies dramatically. Free VPNs often sell your data. Even paid VPNs differ in logging policies, jurisdiction, and technical security. Research before choosing.
Frequently Asked Questions
Can I use a free VPN instead of Tor?
Free VPNs are generally worse than Tor for privacy. Tor is genuinely free and doesn’t need to monetize users. Free VPNs typically sell data, show ads, or provide poor security. If you need free privacy protection, Tor is the better choice.
Is VPN safer than proxy?
Yes. VPNs encrypt your traffic, while most proxies don’t. With a proxy, anyone monitoring the connection can see your traffic. A VPN ensures only you and the VPN server can decrypt it.
Why would someone use a proxy over a VPN?
Proxies can be faster (no encryption overhead), easier to configure for specific apps, and sufficient for low-stakes tasks like bypassing simple geo-blocks. Some use cases like web scraping require rotating proxies that VPNs don’t offer.
Can police track you through Tor?
Tor makes tracking extremely difficult but not impossible. Well-funded adversaries (like nation-states) have occasionally deanonymized Tor users through traffic analysis, browser exploits, or user mistakes. For most threat models, Tor provides excellent protection.
Do I need all three?
Most people need only one – typically a VPN. Using multiple tools is for specific high-security needs. More complexity means more potential mistakes. Choose the right tool for your actual threat model.
Summary
- VPN: Best all-around choice for privacy, speed, and ease of use. Use for everyday protection.
- Proxy: Quick IP hiding without encryption. Use for low-stakes, speed-critical tasks.
- Tor: Maximum anonymity at the cost of speed. Use when anonymity is paramount.
- Most users only need a good VPN
- Never trust free proxies with sensitive information
